Orc Software Launches Co-Located Hosted Algorithmic Derivatives Trading Platform

Firms Can Rapidly Deploy Advanced Custom Algorithmic Strategies on CME, CBOT,
LIFFE, EUREX & ICE.

NEW YORK, Tuesday July 31, 2007 - Orc Software (SSE: ORC), the leading global
provider of technology for advanced derivatives trading and connectivity, today
announced the launch of Orc Liquidator Hosted — an exchange co-located, fully
hosted solution for quickly deploying custom algorithmic derivatives trading
strategies with ultra-low latency.

With Orc Liquidator Hosted firms can focus more on creating advanced futures &
options trading strategies to deploy into the market in weeks, and less on
managing technology. Orc Liquidator is a black box trading platform targeted at
proprietary trading desks at investment banks, trading firms and hedge funds.
Orc Liquidator Hosted is immediately connected to CME, CBOT, LIFFE, EUREX and
ICE. 100+ additional markets can be deployed quickly as required. The service is
co-located with the CME in Chicago, ICE in Atlanta, and in New Jersey.

“Pressure on firms to deploy complex futures and options strategies quickly, and
before another firm seizes the opportunity, is relentless,” said Jesper
Alfredsson, Head of Algorithmic Trading Solutions, Orc Software. “The most
advanced firms also need to co-locate at exchanges in order to minimize latency.
Orc Liquidator Hosted allows firms to put new custom black box style strategies
into the market within weeks. We are also decreasing latency by co-locating at
the exchange, and lessening the IT burden by fully managing the server and
network connectivity.”

Orc Liquidator is a black box trading system that allows the rapid deployment of
custom trading strategies at a processing speed of over 20,000 orders per second
with sub-millisecond latency.  Among the custom strategies commonly deployed on
Liquidator are cross market futures strategies and multiple leg spread
strategies, pairs trading, volatility trades, currency cash and futures
arbitrage, local exchange vs. ADR with currency hedge, and warrants market
making.  Orc Liquidator has connectivity to over 100 exchanges worldwide.

The monthly fee for Orc Liquidator Hosted includes a powerful high speed
dedicated server, co-location at the exchange, Liquidator and market gateway
software, network connectivity to each market, network connectivity to the
customer over any telco including BT Radianz, TNS, Savvis, Yipes and Wave2Wave,
and full hosting services including management and support. 

Orc Liquidator Hosted is hosted at the Equinex facilities in Chicago in the same
building as the CME matching engine, and also in New Jersey and Atlanta.
Connectivity to CME is through the ultra low latency LNET connection.

Orc Software is next exhibiting at the FOREX Network, 25-26 September 2007, in
Chicago.
